WARNING!

excessive wear or unpredictable braking. You might
not have full braking power when you need it to
prevent an accident. If you have been operating your
vehicle in dirty conditions, get your brakes checked
and cleaned as necessary. Failure to do so may result
is serious injury.
PARKING BRAKE
When the parking brake is applied with the
ignition on, the Brake Light in the instrument
cluster will come on.
NOTE: This light only shows that the parking brake is
on. It does not show the degree of brake application.
If the parking brake is applied while the vehicle is
moving, a chime will sound to alert the driver. The chime
will sound up to 10 times or until the vehicle has
returned to a stop.
Before leaving the vehicle, make sure that the parking
brake is set. To set the parking brake, pull up firmly on
the lever. Also place the gear selector in the Park position
(automatic transaxle) or Reverse (manual transaxle). To
release the parking brake, apply the brake pedal, pull up
slightly on the lever, then depress the button on the end
of the lever and push the lever fully down toward the
floor.
NOTE: The parking brake lever will not release unless
the lever is pulled up slightly past its applied position.
